Ferme de la Josiere<\/h2>\n\n\n\n

La centrale de la Josi\u00e8re est install\u00e9e \u00e0 Chaucre, Saint-Georges d’Ol\u00e9ron, avec une surface de 170 m2 et une puissance de 22,5 kWc. La production pr\u00e9visionnelle est d\u2019environ 28000 kWh par an.<\/h6>\n\n\n\n

Nous avons sign\u00e9 la convention de mise \u00e0 disposition de la troisi\u00e8me toiture le 14 d\u00e9cembre 2020 avec la ferme de \u00ab La Josi\u00e8re \u00bb qui construisait l\u2019extension d\u2019un hangar. L\u2019installation photovolta\u00efque figurait au permis de construire et n\u2019avait donc pas besoin d\u2019une autorisation compl\u00e9mentaire de l\u2019urbanisme.<\/p>\n\n\n\n

L’installation est expos\u00e9e sud-est. Le pan de la nouvelle toiture est diff\u00e9rent de l\u2019ancienne ce qui provoque ces ombres port\u00e9es sur la surface \u00e0 \u00e9quiper de PV. En fonction des plans de toitures, l\u2019apparition d\u2019ombres port\u00e9es se fera en fin de journ\u00e9e.<\/p>\n<\/div><\/div>\n\n\n\n

Pour optimiser notre installation malgr\u00e9 ces ombres, nous avons relev\u00e9 le 1er et le 15 de chaque mois gr\u00e2ce au logiciel Sketchup l\u2019ombre port\u00e9e au coucher du soleil et l\u2019heure de d\u00e9but de l’ombre, soit 30 mesures. Ensuite, nous avons analys\u00e9 l\u2019amplitude de ces donn\u00e9es \u00e0 une p\u00e9riode (fin de journ\u00e9e) o\u00f9 l\u2019installation photovolta\u00efque ne donne plus que 15 % de sa puissance.<\/p>\n\n\n\n

Est-ce que l\u2019apparition de ces ombres a une r\u00e9elle incidence sur l\u2019ensemble de la production ? Nous pensons que nous gagnerions beaucoup \u00e0 supprimer la premi\u00e8re rang\u00e9e de panneaux photovolta\u00efques pr\u00e8s du pignon de l\u2019ancien b\u00e2timent mais demandons confirmation \u00e0 la soci\u00e9t\u00e9 SunPvconsult, Monsieur Thomas Lacaille, qui  valide notre \u00e9tude un peu empirique.<\/p>\n\n\n\n

De toute fa\u00e7on, les onduleurs SMA embarquent une nouvelle technologie \u00ab Shadefix \u00bb qui r\u00e9glerait le probl\u00e8me d\u2019une fa\u00e7on logicielle et gratuite permettant ainsi d\u2019optimiser la production en cas d\u2019ombres port\u00e9es.<\/p>\n\n\n\n

Notre exp\u00e9rience sur les deux pr\u00e9c\u00e9dents chantiers, ainsi que l\u2019implication totale des propri\u00e9taires, nous a permis de r\u00e9aliser ce chantier de mani\u00e8re optimale.<\/p>\n\n\n\n

L\u2019injection de l\u2019\u00e9lectricit\u00e9 produite a d\u00e9but\u00e9 le 10 novembre 2021 soit 11 mois seulement apr\u00e8s la signature de la convention.<\/p>\n\n\n\n
